Watch: ‘The Simpsons’ Lego Episode Gets Full Trailer

“Is it just me or does something feel weird today?” asks Bart Simpson in the new trailer for Sunday’s episode of “The Simpsons.”

Something is definitely off — the characters, the items and all of Springfield have been Lego-fied. The upcoming 550th episode of the cartoon, dubbed “The Simpsons’ Lego Spectacular,” finds Homer Simpson torn between two alternate realities: The Lego one and the 2D, hand-drawn one of usual. When Homer gets his hands on a magical board game, named Perky Patty Princess Shop, it reveals to Homer to 2D world, and he embarks on an adventure to fix the blocked-up Springfield.

It all looks similar to “The Lego Movie,” which combined 3D Lego animation with live action, whereas the episode incorporates 2D animation against the 3D. “The Simpsons” recently hit a ratings low, but it’s possible the Lego theme could help. “The Lego Movie” was a huge blockbuster hit, grossing $452 million worldwide and receiving rave reviews.

Fox had teased some of the episode before the release of the full trailer, and had even given a glimpse at the Simpsons-themed minifigures last month. The episode, “Brick Like Me,” will air May 4 at 8p.m. on Fox.

Any connection to “Perky Pat”, the Barbie-like doll and accessories featured in Philip K. Dick’s novel The Three Stigmata of Palmer Eldritch? Collectors would buy the doll and expensive accessories for the doll, then take a certain drug. The drug let them enter the world of Perky Pat. It was a much nicer world than the one they were living in.
